TONER
摘要:
A toner comprising a toner particle including a binder resin, wherein in a temperature T (°C) - storage elastic modulus G' (Pa) curve obtained by measuring the toner with a rheometer, a storage elastic modulus G' (80°C) at 80°C is from 2.0 × 10 3 Pa to 2.0 × 10 5 Pa; and a local minimum value of a change amount (dG'/dT) of a storage elastic modulus G' in a range of 60°C to 80°C with respect to a temperature T is -1.0 × 10 6 or less, and when the temperature of the toner is raised, where a projected area of the toner at 80°C is S 1 µm 2 ), a radius of the projected area of the toner at 80°C is R 1 (µm), and a projected area of the toner at 120°C is S 2 (µm 2 ), the S 1 , R 1 and S 2 satisfy a following formula (1): S 2 / S 1 × 1 / R 1 ≤ 0.22.
